Scaling is an issue that Blocktrades is constantly thinking about.
If we were Web 2.0, we might be in trouble at the moment. But, scaling is to the point where we can handle tens of millions of transactions, at least in testing. So I am sure they are running ahead of the curve for now.
Some are proposing the idea of using off chain storage also. Does every LOL need to be on chain?
That's good to know. The idea of off chain storage is interesting. Some might argue that it would defeat the purpose and advantage of the blockchain. I'm thinking why not combine both. If there are instances where transaction processing is slowing down, maybe we can use off chain storage as a waiting are until the processing can catch up and go back to normal.
